If this murdered Sergi is the same person mentioned in the older articles, again, his having moved from Brampton to Etobicoke is a bit odd but certainly not an impossibility. Over the decades, Brampton has been home to some important or known made members of the Siderno Group ('ndrangheta), e.g., Cosimo Stalteri, Domenico Ruso, Vincenzo Raco. If this Sergi is Calabrian--the surname certainly is--he could be a Siderno Group associate.
